Description
The display shows 0 0 0.
Each "0" indicates one of the paths that the disk
transport mechanism follows in front of each
stack of optical disks. If the path is clear, a "0"
displays; if the path is blocked (because of an
optical disk that is not inserted fully into its
storage slot for example), an "*" will be
displayed. This display is automatically
updated if the status changes.
Reports THUMB A, THUMB B, or NO THUMB.
Looks at the top and bottom thumb sensors and
reports whether the thumbs on the disk
transport mechanism are in the forward or back
position. If THUMB A or THUMB B is returned,
the specified thumb is the forward position. If
NO THUMB is returned, both thumbs are in the
back position.
Reports ON or OFF. Looks at the top thumb
sensor which reports whether or not the thumb
that is currently on the top side of the disk
transport mechanism is in the forward position.
If ON is reported the thumb is in the back
position; if OFF is reported the thumb is in the
forward position.
Reports ON or OFF after checking the translate
calibration sensor. (Display automatically
updates if the status changes.)
